GAs-rnonucnn FOR FURNACES.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed February 9, 1914. Serial No. 817,384.

To all whom it may concern:

Be it known that I, VVILLIAM O. HOUSTON, a citizen of the United Statesof America, and resident of Bellaire, county of Belmont, and State ofOhio, have invented certain new and useful Improvements in Gas-Producersfor Furnaces, of which the following is a specification.

This invention relates broadly to furnaces, and specifically to aproducer wherein gases are generated and directed to a combustionchamber.

The primary object of the invention is to provide a furnace of thegas-producer type which is of simple construction and which has a pairof fire-boxes arranged side by side, both in open communication with thecombustion chamber, and which are separately fired, thus assuring aconstant production of gas in such quantities as will prevent anyserious reductions in the temperature of the heating chamber.

As is well known, when gas is furnished to the combustion chamber from asingle fire-box, constant care must be exercised to keep the fuel bed ingood gas-producing condition, and inattention frequently results in thefuel becoming packed and the fire smothered, retarding the production ofgas to such an extent that the temperature of the heating chamber ismaterially lowered, ofttimes with seriously detrimental results,particularly in furnaces of a mufiie type wherein a substantiallyuniform temperature is required.

It is therefore the purpose of the present invention to provide afurnace whereby the above recited objection is obviated and thepossibility of an undue lowering of the temperature is reduced to aminimum.

The invention resides in the features of construction, arrangement ofparts and combination of elements which will hereinafter be fullydescribed, reference being bad to the accompanying drawing, forming apart of this specification, in which- Figure 1 is a longitudinal sectionof the invention; and Fig. 2 is a view partially in front elevation andpartially in transverse section on the line 2-2, Fig. 1.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several.views1 1 indicate theopposite side-walls, 2 the rear end wall, and 3 the crown of a gasproducer which is divided longitudinally by a central wall 4i to formtwo separate fire-boxes 5, both of which communicate through a passage 6wlth a passage 7 leading to the combustion chamber (not shown). A set ofgrate-bars 8 provided in each fire-box supports the fuel-bed therefor,and said fire-boxes are fed separately, as from suitably arrangedhoppers 9, or in any other suitable manner. Neither fire-box having anydirect connection with the other, each must be attended separately, andeach furnishes its quota of the gas required for maintaining the furnaceat a proper high temperature. As will be understood, it is highlyimprobable that the fires in both fire-boxes would in any case becomeclogged or rendered inefficient at the same time. Thus, when the fire inone of said fire-boxes dies down from any cause, the other fire will bein condition to furnish a sufficient volume of gas to maintain arelatively high temperature in the heating chamber of the furnace, andwill, particularlyif accelerated somewhat, supply gas in ample volume tomaintain the required temperature until the fire in the one fire-box hasbeen restored to proper condition.

Provided in the opposite side-walls 1, in the rear-end wall 2 and in thedivision wall 4 is a series of connected or communicating flues 10 whichare adapted to permit of a circulation of cold air by means of whichsaid walls are maintained in a relatively cool condition, preventing therapid destruction or deterioration of said walls which would otherwiseresult due to the excessive heat to which they are subjected.

What is claimed is In a gas producer for furnaces, a pair of side walls,a division wall between said walls and constituting with the latterfire-boxes, an arched crown extending over and supported centrally bysaid division wall and having its ends extending over the respectivefire-boxes and supported by the respec tive side walls, a rear wallcommon to each of the fire-boxes and having a horizontalpassage formedtherein which passage extends across the rear end of the division walland which has its ends communicating with the respective fire-boxes, andterminating at points central between the side and division having a topWall supported by the top of Walls, said crown forming the top Wall thecrown. 10 which defines the top. of said passage,and a In testimonywhereofll afiix my signature passage extending from the horizontal pas.-in presence of two subscribing Witnesses.
